From: stew%lhasa.UUCP@harvard.ARPA From a recent article in Computer Technology Review by three senior engineers from DEC: "At the CPU board level, the performance of the MicroVAX I is superior to the VAX-11/730 at about half its power consumption and printed circuit board space. Depending on the application, the performcance of the MicroVAX I is about 60% of the VAX-11/750 at about 20% of its cost. An original design constraint that influenced that influenced a number of decisions in the design process was a short time-to-market. The main results were the selection of an existing systems package and extremely tight limits on the design of the CPU." The article continues with quite a long, technical discussion of the implementation. It claims a 70% cache hit rate, further improved by block-mode transfers and an instruction prefetch queue. Stew

From: decwrl!mcdaniel@UCB-VAX (Gene McDaniel) I think most of the net debate about MicroVax pertains to the MicroVax II chip set. I believe some material has been published about it, however I don't have the references. MicroVax I is an existing product, and I am not sure if there is a product annonucement about MicroVaxII or not. Gene
